Click the drop-down arrow next to “Firms,” then select MORE OPTIONS.
![Patent-Tip-41.2](https://help.docketnavigator.com/wp-content/uploads/2023/09/Patent-Tip-41.2.png)
To enter your first firm as representing the Plaintiff, set the firm role as Plaintiff. Then click SAVE.
![Patent-Tip-41.3](https://help.docketnavigator.com/wp-content/uploads/2023/09/Patent-Tip-41.3.png)
Begin typing your firm name and select it from the drop-down suggestions that appear.
![Patent-Tip-41.4](https://help.docketnavigator.com/wp-content/uploads/2023/09/Patent-Tip-41.4.png)
Next click the plus icon next to the Plaintiff role to enter a second firm name, choosing Defendant as the role this time. Notice this creates an “and” operator between the firms.
![Patent-Tip-41.5](https://help.docketnavigator.com/wp-content/uploads/2023/09/Patent-Tip-41.5.png)
View your results and then run another Cases search, this time reversing the firms’ roles. The end result should look something like this:
Paul Hastings representing Plaintiff against Finnegan
Finnegan representing Plaintiff against Paul Hastings
Note: Using the Plaintiff and Defendant roles will by default restrict your results to USDC cases. If you want to include PTAB or ITC cases, use the Patentee/Patent Challenger roles instead.
